CrunchDeals: 4GB Bluetooth MP3 player for $39.99

insignia is selling the refurbished 4GB Insignia Sport in red, black, and blue for $39.99 when you use code NS4V at checkout. The Sport is a fairly straightforward portable media device that plays music and videos and displays photos, but it’s also got an added feature that you won’t find on most other devices of its kind: Bluetooth.

So if you’ve got some Bluetooth headphones, the Sport might make for some inexpensive wireless audio goodness. Other features include OGG support, 1.7-inch color screen, FM-tuner, and memory expansion via microSD cards.

The promo code (NS4V) is good until the end of November.
